+## Introduction
+The shadow-utils package includes the necessary programs for
+converting UNIX password files to the shadow password format, plus
+programs for managing user and group accounts. The pwconv command
+converts passwords to the shadow password format. The pwunconv command
+unconverts shadow passwords and generates a passwd file (a standard
+UNIX password file). The pwck command checks the integrity of password
+and shadow files. The lastlog command prints out the last login times
+for all users. The useradd, userdel, and usermod commands are used for
+managing user accounts. The groupadd, groupdel, and groupmod commands
+are used for managing group accounts.

 all in this directory.  I haven't tested them, use at your own risk.
 Anyway, the best one I've seen so far is adduser-3.x from Debian.

-atudel is a perl script to remove at jobs owned by the specified user
-(atrm in at-2.9 for Linux can't do that).
-
 udbachk.tgz is a passwd/group/shadow file integrity checker.

-** shadow-adduser 1.2:
-** I took the C source from adduser-shadow (credits are below) and made
-** it a little more worthwhile.  Many small changes... Here's
-** the ones I can remember:
-** 
-** Removed support for non-shadowed systems (if you don't have shadow,
-**     use the original adduser, don't get this shadow version!)
-** Added support for the correct /etc/shadow fields (Min days before
-**     password change, max days before password change, Warning days,
-**     and how many days from expiry date does the account go invalid)
-**     The previous version just left all of those fields blank.
-**     There is still one field left (expiry date for the account, period)
-**     which I have left blank because I do not use it and didn't want to
-**     spend any more time on this.  I'm sure someone will put it in and
-**     tack another plethora of credits on here. :)
-** Added in the password date field, which should always reflect the last
-**     date the password was changed, for expiry purposes.  "passwd" always
-**     updates this field, so the adduser program should set it up right
-**     initially (or a user could keep thier initial password forever ;)
-**     The number is in days since Jan 1st, 1970.
-**
-**                       Have fun with it, and someone please make
-**                       a real version(this is still just a hack)

-X.TH GROUPMEMS 8
-X.SH NAME
-groupmems \- Administer members of a user's primary group
-X.SH SYNOPSIS
-X.B groupmems
-\fB-a\fI user_name \fR |
-\fB-d\fI user_name \fR |
-\fB-l\fR |
-\fB-D\fR |
-[\fB-g\fI group_name \fR]
-X.SH DESCRIPTION
-The \fBgroupmems\fR utility allows a user to administer their own
-group membership list without the requirement of superuser privileges.
-The \fBgroupmems\fR utility is for systems that configure its users to
-be in their own name sake primary group (i.e., guest / guest).
-X.P
-Only the superuser, as administrator, can use \fBgroupmems\fR to alter
-the memberships of other groups.
-X.IP "\fB-a \fIuser_name\fR"
-Add a new user to the group membership list.
-X.IP "\fB-d \fIuser_name\fR"
-Delete a user from the group membership list.
-X.IP "\fB-l\fR"
-List the group membership list.
-X.IP "\fB-D\fR"
-Delete all users from the group membership list.
-X.IP "\fB-g \fIgroup_name\fR"
-The superuser can specify which group membership list to modify.
-X.SH SETUP
-The \fBgroupmems\fR executable should be in mode \fB2770\fR as user \fBroot\fR
-and in group \fBgroups\fR.   The system administrator can add users to
-group groups to allow or disallow them using the  \fBgroupmems\fR utility
-to manager their own group membership list.

- * pwdauth.c - program to verify a given username/password pair.
- *
- * Run it with username in argv[1] (may be omitted - default is the
- * current user), and send it the password over a pipe on stdin.
- * Exit status: 0 - correct password, 1 - wrong password, >1 - other
- * errors.  For use with shadow passwords, this program should be
- * installed setuid root.
- *
- * This can be used, for example, by xlock - you don't have to install
- * this large and complex (== possibly insecure) program setuid root,
- * just modify it to run this simple program to do the authentication.
- *
- * Recent versions (xlockmore-3.9) are cleaner, and drop privileges as
- * soon as possible after getting the user's encrypted password.
- * Using this program probably doesn't make it more secure, and has one
- * disadvantage: since we don't get the encrypted user's password at
- * startup (but at the time the user is authenticated), it is not clear
- * how we should handle errors (like getpwnam() returning NULL).
- * - fail the authentication?  Problem: no way to unlock (other than kill
- *   the process from somewhere else) if the NIS server stops responding.
- * - succeed and unlock?  Problem: it's too easy to unlock by unplugging
- *   the box from the network and waiting until NIS times out...

-Hello Marek,
-
-I have created a diffile against the 980403 release that adds
-functionality to newusers for automatic handling of users with only
-anonymous ftp login (using the guestgroup feature in ftpaccess, which
-means that the users home directory looks like '/home/user/./'). It also
-adds a commandline argument to specify an initial directory structure
-for such users, with a tarball normally containing the bin,lib,etc
-directories used in the chrooted environment.
-
-I am using it to automatically create chunks of users with only ftp
-access for a webserver.
-
-I have tried to follow your coding standards and I believe it is bug
-free but.. well, who knows. :) It's not much code however.
-
-I hope you find it useful. Do what you like with it, feel free to ask if
-anything is unclear.

-Best rgds,

-This is my wishlist for the shadow suite, in no particular order.  Feel
-free to do anything from this list and mail me the diffs :-).
-
-Patches in diff -u format, against the latest version (sometimes in the
-"beta" directory) are preferred and make my job easier.  Please, no
-MIME, base64, quoted-printable, or HTML.  For very big patches, or if
-your mailer can corrupt them, please use gzip and uuencode.  Thanks!
-
-New ideas to add to this list are welcome, too.  --marekm
-
- fix all the bugs, of course
- implement "su only" accounts (no logins, only su from other account)
- rewrite getdef.c to be more general? (no hardcoded names)
- patch for rlogind/telnetd to create utmp entry and fill in ut_addr
- option to specify encrypted password in passwd (for yppasswdd, so it
-  doesn't need to know about shadow/non-shadow); should probably use a pipe
-  (less insecure than command line arguments)
- add support for changing NIS passwords
- add option to check passwords by piping them to external programs
- add functionality of the contrib/rpasswd.c wrapper to passwd
- option to generate pronounceable passwords (like on SCO), external program?
- poppassd (remote password change for eudora etc.)
- add support for passwd/shadow db files (glibc)
- vipw: check password files for errors after editing
- add "maximum time users allowed to stay logged in" limit option to logoutd
- handle quotes in /etc/environment like the shell does (but sshd doesn't...)
- better utmpx support (logoutd, ...)
- better OPIE support (report number of logins left, etc.)
- new option for /etc/suauth: don't load user's environment (force "su -")
-  suggested by Ulisses Alonso Camaro
- find out why recent releases won't compile on Solaris
- newusers should be able to copy /etc/skel to the new home directory
-  (like useradd)
- add directories where other packages can add hooks for package-specific
-  per-user configuration, to be executed with run-parts. Some hooks should
-  be executed at package install time for existing users, likewise for
-  package removal and possibly modification.  (Debian Bug#36019)

+ *   agetpass()
+ *	This function is very similar to getpass(3).  It has several
+ *	advantages compared to getpass(3):
+ *
+ *	- Instead of using a static buffer, agetpass() allocates memory
+ *	  through malloc(3).  This makes the function thread-safe, and
+ *	  also reduces the visibility of the buffer.
+ *
+ *	- agetpass() doesn't reallocate internally.  Some
+ *	  implementations of getpass(3), such as glibc, do that, as a
+ *	  consequence of calling getline(3).  That's a bug in glibc,
+ *	  which allows leaking prefixes of passwords in freed memory.
+ *
+ *	- agetpass() doesn't overrun the output buffer.  If the input
+ *	  password is too long, it simply fails.  Some implementations
+ *	  of getpass(3), share the same bug that gets(3) has.
+ *
+ *	As soon as possible, the password obtained from agetpass() be
+ *	erased by calling erase_pass(), to avoid possibly leaking the
+ *	password.
+ *
+ *   agetpass_stdin()
+ *	This function is the same as previous one (agetpass). Just the
+ *	password is read from stdin and terminal is not required.
+ *
+ *   erase_pass()
+ *	This function first clears the password, by calling
+ *	explicit_bzero(3) (or an equivalent call), and then frees the
+ *	allocated memory by calling free(3).
+ *
+ *	NULL is a valid input pointer, and in such a case, this call is
+ *	a no-op.
+ *
+ * RETURN VALUE
+ *	agetpass() returns a newly allocated buffer containing the
+ *	password on success.  On error, errno is set to indicate the
+ *	error, and NULL is returned.
+ *
+ * ERRORS
+ *   agetpass()
+ *	This function may fail for any errors that malloc(3) or
+ *	readpassphrase(3) may fail, and in addition it may fail for the
+ *	following errors:
+ *
+ *	ENOBUFS
+ *		The input password was longer than PASS_MAX.
+ *
+ * CAVEATS
+ *	If a password is passed twice to erase_pass(), the behavior is
+ *	undefined.

+	 * the terminating '\0'.  We also want to detect truncation, and
+	 * readpassphrase(3) doesn't detect it, so we need some trick.
+	 * Let's add one more byte, and if the password uses it, it
